Fun fact, I communicated with aforementioned biologists via email (and later Facebook) before we met IRL . There never has been any need for calling each other rude names. On the contrary, most of them are so extremely polite that now and then I feel uncomfortable. I can't even call myself an amateur arachnologist yet they have always treated me with respect, and replied to my questions without all the "U n00b" and "U 1user" attitude I constantly see in IT.
I am a member of several Facebook groups (on arachnids, on orchids, etc.) and most of the time the discussions are friendly and polite. The total amount of abrasive attitude one can find in the comments to a single Slashdot posts between people, even excluding ACs, I haven't seen in all those groups together for years. Oh, and there are plenty of females in those groups. Maybe that's no coincidence?
 Another fun fact, I met my wife online, also.
Because pre-calculated tables exist it's good practice to add a "salt" to the password. Otherwise one just calculates the hash value of '1234567' and looks in the results for this hash value.
If I had my way we'd do everything as version controlled Markdown, but I'll never get my way.
I use Org mode for documentation, I prefer it over Markdown.
